Its called the catastrophic alignment or planetary alignment
One-dimensional
"Line of best fit"
The imaginary line that extends straight out from the center of a reflective surface is the optical axis.
a straight line joining the ends of an arc
false slope of line is co-efficient of x term ,when line equation expressed in standard form y=mx+c
Gig line.
A straight line on the Cartesian plane is the graph of a linear equation.
An allineation is an alignment - the positioning of two or more things in a straight line, such as of two planets with the sun.
There is always a problem with using the term Planetary alignment. How close do you want the planets to be in alignment. Do you include the ecliptic? If you want all the planets to be aligned in a straight line with only a 1 mile difference, then you'll have a wait a long long while - probably infinity. Even then, you have to take into account the ecliptic as space is 3 dimensional, so the planets will never align in a perfect straight line as seen from Earth. The last "close" alignment was in May 2000 and nothing happened then.

you guys dont know me eitherA translationTranslationA translation is movement of a figure to a new position along a straight line.
